Abstract
The invention relates to compound tubes, in particular to a steel-tube coral concrete member amongst the compound tubes. The steel-tube coral concrete member comprises a steel tube filled with coral concrete. The steel-tube coral concrete member has the advantages that the problems that the coral concrete is low in strength and cohesiveness of aggregates is poor are solved, the defects of the coral reef are effectively converted into advantages; after coral fragments are mixed into the concrete filled steel tube, hooping of core concrete by the steel tube wall is enhanced, the core concrete is stressed in three directions, overall compression bearing capacity and compressive deformation resistance of the concrete filled steel tube are enhanced to a certain degree, and accordingly properties of the material are given to full play.
Description
Technical field
The present invention relates to clad pipe, relate in particular to a kind of steel pipe coral concrete member in the clad pipe.
Background technology
For a long time; The pattern of China's economic development belongs to resource-hungry; China is in the economic period of greatly developing in addition; Commercial production will produce increasing solid waste-cullet, scrap rubber, burning city domestic garbage lime-ash, therefore, recycle these solid waste and will have important practical significance for china natural resources saving, environmental protection.
At present, coral is applied in the concrete, on the one hand; The space is more in the coral reef chip; Therefore the category that belongs to lightweight aggregate makes that concrete strength reduces, on the other hand; Caking property is not fine between coral reef chip and cement slurry and aggregate, more than the problem of two aspects restricted the application of coral reef in concrete.
Summary of the invention
In order to solve the problems of the prior art, the invention provides a kind of steel pipe coral concrete member.
The invention provides a kind of steel pipe coral concrete member, comprise steel pipe, be filled with coral concrete in the said steel pipe.
As further improvement of the present invention, the closed at both ends of said steel pipe.
The invention has the beneficial effects as follows: through such scheme; Overcome the bad problem of caking property between the lower and aggregate of coral concrete intensity, the shortcoming of coral reef effectively has been converted into advantage, when the coral chip mixes in the concrete filled steel tube; Because steel pipe walls is strengthened the cuff of core concrete; Core concrete is in the three dimension stress state, makes the concrete filled steel tube entire compression bearing capacity and the ability of opposing compressive strain obtain certain enhancing, thereby material property is fully played.
Description of drawings
Fig. 1 is a kind of steel pipe coral concrete of the present invention element cross-section sketch map.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the present invention is further specified.
Drawing reference numeral among Fig. 1 is: steel pipe 1; Coral concrete 2.
As shown in Figure 1, a kind of steel pipe coral concrete member comprises steel pipe, is filled with coral concrete in the said steel pipe, forms solid steel pipe.
As shown in Figure 1, the closed at both ends of said steel pipe 1.
A kind of steel pipe coral concrete member provided by the invention; Application is extensive, mainly is used as compressed member, as send power transformation member, single or multiple lift industrial premises pillar, high level or superelevation layer civilian construction post etc.; Also can be used as flexural member, like arch rib in highway or the Urban Bridge etc.
Coral chip in a kind of steel pipe coral concrete member provided by the invention adopts the coral chip of South Sea islands and reefs; Main component is aragonite and high-magnesian calcite; Calcium carbonate content is up to more than 96%; Coral reef is simply smashed to pieces processing, directly the coral reef chip directly is incorporated in the concrete, the coarse aggregate in the some or all of replacement common steel tube concrete with certain size.Adopt particle diameter be 20 ~ 50mm coral chip in irregular shape as coarse aggregate, the replacement rate is respectively 0%, 20%, 40%, 60%, 80%, 100%, replaces rubble etc. quality, concrete design strength is C30, water/binder ratio W/C is 0.43, sand coarse aggregate ratio β s is 33%.If every cubic meter of concrete mixture quality is 2400kg, benchmark match ratio then, cement: water: sand: stone=453:195:578:1174=1:0.43:1.28:2.59.The steel pipe sample dimensions is D * L * t=133mm * 400mm * 4mm; Wherein the bottom is with the cover plate welding that is of a size of 160mm * 160mm * 6mm; After the concrete filled steel tube cast is good; The contraction of 2 ~ 3mm can appear, adopt high-strength mortar to polish to treat it to solidify after, with the cover plate welding that is of a size of 160mm * 160mm.Behind the inner concrete curing 28d, can reach design strength basically.Under the effect of axial compression; 1 pair of inner concrete of outside steel pipe provides the hoop effect of contraction; Make core concrete be in the state of three dimension stress, can improve its compressive strength greatly, simultaneously steel pipe 1 inner fill concrete; Avoid steel pipe generation unstability, thereby improved the whole mechanical property of member.
A kind of steel pipe coral concrete member provided by the invention is applied in the common steel tube concrete, the composite steel tube concrete component of processing with the coarse aggregate in the some or all of replacement common steel tube of the coral reef chip concrete.
The advantage of a kind of steel pipe coral concrete member provided by the invention is:
1. overcome the bad problem of caking property between the lower and aggregate of coral concrete intensity, the shortcoming of coral reef effectively has been converted into advantage.
When the coral chip mixes in the concrete filled steel tube; Because steel pipe walls is strengthened the cuff of core concrete; Core concrete is in the three dimension stress state; Make the concrete filled steel tube entire compression bearing capacity and the ability of opposing compressive strain obtain certain enhancing, thereby material property is fully played.
2. the extensive application of coral reef is in concrete filled steel tube; Gathering materials on the spot for the coastal islands and reefs of China provides an effective way, and the coastal islands and reefs sandstone aggregate of solution relies on the condition on land for a long time, simultaneously; Also realize the recycling of material, met the national medium-term and long-term strategy of sustainable development.
3. should invention easy construction, simple to operate, service behaviour is good, can be in actual engineering large-scale application.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
Claims (2)
1. a steel pipe coral concrete member is characterized in that: comprise steel pipe, be filled with coral concrete in the said steel pipe.
2. steel pipe coral concrete member according to claim 1 is characterized in that: the closed at both ends of said steel pipe.
